Atrial fibrillation (AF) after transcatheter closure of patent foramen ovale (PFO) is not a rare complication. However little is known about the effect of atrial septal device implantation… (More)

BACKGROUND
Diastolic dysfunction of the right ventricle (RV) is common after repair of tetralogy of Fallot. While restrictive physiology in late diastole has been well known, dysfunction in early… (More)

OBJECTIVES
We sought to evaluate the course of cardiopulmonary function after transcatheter atrial septal defect (ASD) closure and to identify the physiopathologic mechanisms leading to this change.… (More)

This viewpoint article discusses the potential for incorporation of atrial defibrillation capabilities in modern multi-chamber devices. In the late 1990s, the possibility of using shock-only therapy… (More)
